Relative velocity in Mean Free Path problems

Click For Summary
SUMMARY

The average relative velocity in Mean Free Path problems is established as equal to the square root of 2 times the magnitude of the x-direction velocity. This relationship is crucial for understanding gas behavior, particularly in the context of Ideal gases and Van der Waals gases. The discussion references the kinetic theory of gases, emphasizing the mathematical derivation of relative velocity in gas collisions. For further insights, the HyperPhysics resource on kinetic theory is recommended.

Why is average relative velocity equal to the square root of 2 times the magnitude of the x direction velocity?

I'm trying to solve some problems that deal with gas laws from Ideal gases to the Van der Waals gases.

Does anybody have any ideas?

Thanks.
